Interesting. The reason I mentioned to check visually is because the adjustment didn't "last" or work on all 3 bikes. I just figured I did something wrong being in a hurry and not visually verifying, so this was on my "to do list" to look into. I know the technique worked on my other bikes, but your post makes a lot of sense, and it's binding. I wonder if we should also lube or use antiseize on the "oval" part of that "bushing". It would probably float and not bind, like MX breaks float, blue loctite gel would probably ensure nothing shakes loose. Thanks for sharing!
